There's a smell about this so close to the US election.

It sounds like someone is worried about people buying personal radios for Meshtastic or LoRa to use in case cell phone service doesn't work at protests, or there is unrest if the election results are called into question by the current political establishment that doesn't want to cede power. So they got eBay to roll over and more companies could follow.

Ordinarily I wouldn't take a conspiracy theory like this seriously. But in these times, corruption is so rampant that the most convoluted answer tends to be the right one.
